That's the same exhaust I'm looking to get also. Let me know how it is if you happen to get it. I would rejet the carb though.
ok im geting it around aug im puting some money in to my truck
isn't the condition of your plug(color on plug insulator) and condition of exhaust(soot/carbon, etc. in pipe) gonna tell you if you need to tune jets?
Checking plugs on a 4 stroke is useless, just go by how well it runs, and if it's poping. Once you get a VERY slight pop on decel, you're perfect. If you don't need to rejet, then there is no gain.
